Repair of a harp class

My daughter Elizabeth studies in a musical school in Kyiv. She plays harp. Unfortunately, the harp class is a cold and grim place. Its window and wallpapers are over 30 years old, while the building is over 100 years. There are cracks in the ceiling. And the floor is a total mess. The school doesn't get enough funding, so we need to do the repair on our own. Unfortunately, there are only 6 of us, all parents with kids. One is single mom, the other one is on maternity leave. The new window will solve the problem with temperature in winter (it can get up to -30 Celcius outside here).

$1,300 is not a large sum, if it is funded by many. But it is really big for us, especially in summer, when you want to take your kid to some nice place on vacation.

Thanks, everyone! I really hope this will help!
